Tempering process consists of the heat treatment to which we submit our glasses in order to give them mechanical and thermal resistance properties, turning an ordinary glass into a safety glass.
Technically, what we do is heat gradually float up to a temperature of softening of 650 Celsius glass, then cool it quickly with air.
This way will get that glass is exposed on its surface to compression stress and inside to traction stresses, giving greater structural strength and impact than glass thermally untreated.
Giving birth in this way to our safety glass:
